With regards to GRT visibility.. There's another game that has huge, towering "things" in it, which also focuses on exploration etc. That game is CubeWorld. There are "rocks", as they are called in the game, and these rocks would be about 100m high. There is a limited view distance in the game and when you do come across these things in the game, there is a real sense of awe and a little bit of anxiety in just how you are going to manage to climb to the top of it. It's a really satisfying part of the game to climb up the sides of these "rocks" and find the boss on top to do battle with. There are other large things in the game too and it really adds to the awe and wonder when exploring.. so I think that the GRT could provide this same sense of awe and wonder too.
